I'm running an alpine linux box, and am trying to install radare2. I downloaded the git repo, then ran the install.sh script. It seems to run fine until running into an error:

In file included from p/native/linux/linux_debug.c:6:
/home/nomad/GitRepos/radare2/libr/include/r_debug.h:609:115: note: expected 'r_ptrace_data_t' {aka 'int'} but argument is of type 'void *'

compilation terminated.

make[2]: *** [Makefile:157: debug] Error 2
make[1]: *** [Makefile:28: all] Error 2
make: *** [Makefile:61: all] Error 2

I've had a look around online, but haven't been able to find much relating to "Error 2". From the error it looks like I'm missing a library, but I'm not sure what library it is, or how to install it as I'm relatively new to alpine linux.

  • fatal error: asm/ptrace.h: No such file. .... Is a kernel header. Example location: `/usr/src/kernel-devel-5.0.2//arch/x86/include/asm/ptrace.h´ Commented Sep 18, 2019 at 10:53

On Alpine Linux, the asm/ptrace.h header is provided by the linux-headers package.

For installing the Linux headers package, run the following:

apk add linux-headers

Then, try repeating the install process.
